Indlela Yokulungisa Amapharamitha ku-CO2 Welding

Ukulungiswa kwemingcele yenqubo ye-carbon dioxide gas shielded welding: Kunamapharamitha wenqubo amaningi athinta ukushisela okuvikelwe kwegesi ye-carbon dioxide, kodwa okuwukuphela kwawo ama-welders angakwazi ukuzilungisa ngokwawo yi-welding voltage, i-welding current, i-wire diameter, izinga lokugeleza kwegesi, nokwelulwa kwentambo. ubude; Amanani okubhekisela kumapharamitha wenqubo yokushisela: Amadayamitha ocingo avame ukusetshenziswa angu-1.2mm no-1.0mm, ngaphezu kuka-1.6mm no-0.8mm. Kunzima ukuhlangana nezintambo zokushisela zamanye ama-diameter. I-Carbon dioxide gas shielded welding isebenzisa uguquko lwesiyingi esifushane, ngakho-ke indawo yokushisela ye-diameter ngayinye yocingo lokushisela ibanzi. Kule ndawo, i-welding current kanye ne-welding voltage kumele ifaniswe.

Inqubo yokusebenza yokulungisa ukucaciswa kwe-welding: Lungisa okwamanje kanye ne-voltage yomshini wokushisela ngokuya ngale nqubo elandelayo;

1. Vula i-valve ye-cylinder yegesi evikelayo futhi uqinisekise ukuthi ukucindezela kwesilinda segesi kuyinto evamile; Vula amandla omshini wokushisela futhi uqinisekise ukuthi i-flowmeter yokushisa nokunciphisa ingcindezi iyasebenza; Shisisa imizuzu emi-5;
2. Vula i-package yentambo yokushisela, faka i-welding wire reel ku-reel shaft yomshini wokuphakela izintambo, vula isibambo sokubopha, bese usebenzisa amapulangwe ukuze usike ikhanda lentambo yokushisela ekhanda eliyisicaba. Ikhanda locingo lokushisela kufanele lifakwe ngokuvundlile esondweni le-groove le-wire feeding roller ukusuka ngaphansi kwe-reel ye-welding wire; Faka ipayipi lokuphakela ngocingo;
3. Vala isibambo se-clamping, ubeke isibhamu sokushisela phansi futhi usinwebe ngokugcwele. Cindezela inkinobho emhlophe yokuphakela intambo esheshayo ebhokisini lesilawuli kude ukuze uphakele intambo yokushisela ize ivezwe ku-conductive nozzle. Uma kuyisibhamu esidala sokushisela, ungaqala ususe i-nozzle conductive, bese ucindezela inkinobho encane ukondla ucingo, uluveze, bese ulufaka kabusha; Sebenzisa izidladla ukuze usike isiphetho sentambo yokushisela ibe yi-engeli ebukhali engu-45 degree;

4.Lungisa ipuleti lensimbi lokuhlola, hlola ngeso lengqondo i-voltmeter ne-ammeter yomshini wokushisela, yehlisa ngokuqaphela i-voltage ebhokisini lesilawuli kude ngesandla sakho sobunxele, bamba isibhamu sokushisela ngesandla sakho sokudla, bese uqalisa ukushisela i-arc ensimbi yokuhlola. ipuleti; Uma i-voltage iphansi ngempela, isandla sokudla esibambe isibhamu sizozwa ukudlidliza okunamandla kwekhanda lesibhamu esishiselayo futhi sizwe umsindo wokuvela kwe-arc. Lona umsindo owenziwe lapho i-voltage iphansi kakhulu, isivinini sokuphakela ucingo sishesha kakhulu kunejubane lokuncibilika, futhi i-arc ivutha bese icishwa ucingo lokushisela; Uma i-voltage empeleni iphezulu kakhulu, i-arc ingavutha, kodwa uma ubude be-arc bude kakhulu, ibhola elikhulu elincibilikisiwe lizokwakheka ekugcineni kocingo lokushisela. Uma isivinini sokuncibilika sidlula isivinini sokuphakela ucingo kakhulu, i-arc izoqhubeka ivutha ibuyele ku-conductive nozzle, incibilikisa intambo yokushisela kanye nombhobho wokuhambisa ndawonye, ​​inqamule ukuphakelwa kocingo, futhi icime i-arc. Lokhu kuzodala ukulimala kokubili kwe-nozzle conductive kanye ne-wire feeding mechanism, ngakho-ke kufanele kuqinisekiswe ukuthi i-voltage ayiphezulu kakhulu lapho uqala i-arc;

5. Lungisa i-welding voltage knob, kancane kancane wandise i-welding voltage, usheshise isivinini sokuncibilika kocingo lwe-welding, futhi umsindo oqhekezayo wokuphuka kancane kancane uba umsindo ogelezayo;
6. Bheka i-voltmeter ne-ammeter. Uma i-current iphansi kunevelu enqunywe kusengaphambili, khulisa i-welding current kuqala bese ukhulisa i-welding voltage; Uma i-current iphakeme kune-value enqunywe kusengaphambili, qala unciphise i-voltage ye-welding, bese wehlisa i-welding current;
7. Ubude besandiso bentambo yokushisela: eyaziwa nangokuthi ubude besandiso esomile sentambo yokushisela. Nge-welding evikelwe ngegesi, iyipharamitha ebaluleke kakhulu. Ubude obufanele bokunwetshwa kwentambo yokushisela bunganikeza ukushisa okwanele kokumelana, okwenza kube lula ukwakha nokuguqula amaconsi ancibilikisiwe ekugcineni kocingo lokushisela. Lapho ubude besandiso socingo lokushisela bufushane kakhulu, kuvame ukuchaphazeka okuningi. Ukuba mude kakhulu akukhiqizi kalula nje amaconsi amakhulu, kodwa futhi kuholela ekuvikelekeni okubi.
8. I-Phenomenon lapho i-welding voltage kanye ne-welding current ifaniswe: i-arc ivutha kancane, yenza umsindo ozwakalayo ozwakalayo, ikhanda lesibhamu sokushisela lidlidliza kancane, ubulukhuni buyisilinganiso, ukujika kwe-voltmeter akudluli ku-5V, ukujika kwe-ammeter akudluli ku-30A, futhi akufanele kube nokudlidliza ekubambeni kwesandla; Uma ikhanda lesibhamu sokushisela lizwa lithambile kakhulu futhi cishe akukho ukudlidliza, isibhamu sokushisela singahanjiswa ngokukhululekile. Ngokubuka imaski yobuso, intambo yokushisela intanta ngaphezu kwechibi elincibilikisiwe, yenze ibhola elikhulu elincibilikisiwe ekugcineni, futhi ngezinye izikhathi amaconsi amakhulu ayachaphaza, okubonisa ukuthi i-voltage iphezulu kakhulu; Uma ikhanda lesibhamu sokushisela lizwa kanzima futhi lidlidliza kakhulu, umsindo ophumayo ungazwakala, futhi kukhona ukumelana lapho uhambisa isibhamu sokushisela. Ngokubuka imaski yobuso, uma intambo yokushisela ifakwa echibini elincibilikisiwe futhi isakazeka kakhulu, kukhombisa ukuthi i-voltage iphansi; Kuyinzuzo ukuba ne-voltage ephakeme kancane ukuvimbela ukuhlangana okungaphelele.
9. Ukushisela okuvikelwe kwegesi nge-electrode encibilikayo, ukulungiswa kwe-welding current ukulungisa ijubane lokuphakela ucingo lwe-welding wire, futhi ukulungiswa kwe-welding voltage ukulungisa isivinini sokuncibilika kocingo lokushisela. Uma ijubane lokuphakela ucingo nesivinini sokuncibilika zilingana, i-arc ivutha ngokuqinile.
